Excellent point, sir. I have looked at quite a few from the attic,
later when doing upgrades, and I haven't seen leaks. But NO, I have not
carefully gone back on every install to confirm. No news is good news,
but that still doesn't mean 100% leak free. Also, I'm working in a
drier
To me the reports of not seeing leaks is not terribly reassuring. It’s not
surprising when you consider that enough water has to get past tightly
compacted shingles under an L foot, travel between the threads and the wood
of a tightly threaded lag bolt, and then saturate attic insulation enough
to

flashings, but with literally tens of thousands of solar pool heating

Here is a devils advocate question for everyone (*including myself*) who is
claiming no leaks after x-years.
Are we assuming no leaks because the home/system owner has not reported
any or because there are no water stains on the ceilings below the arrays

Hi All,
In the early days with PV and SWH we didn’t use flashings for most roofs
(except tile). We used L-feet directly to the roofing with butyl (comp) or EPDM
(metal) and pre-filled our holes and covered the attachments with good goop.
We've never had a leak reported from this practice. And,
Definitely flash, didn't do it one time, and it bit me.

That was exactly the failure I anticipated when using flashings. Tearing
up the shingle to shingle adhesive and pulling those nails out is more
disruptive than the actual attachment itself. I'm going to flash on an
upcoming job for legal/ insurance reasons, but not because its better.

First, a sealed L foot is not a sealant only attachment system. It has
quite a bit of surface area beyond the hole just like a flashing, and
has mechanical attachment through the roof to the structure (which a
flashing often does not). I consider an L foot to be a mini flashing

Good question, and worthy of revisiting.
As a contractor and businessman, I am obligated to reduce risk exposure by
